B'EET-o ULTIVATO Rt SPECIFICATION forming part of Letters Patent No.498,241, dated May 30, 1893.

Application {iled August 5, 1891.

To all whom it may concern:

Be it known that I, GEORGE G. CROWLEY, a citizen of the United States,residing at Batavia, in the county of Genesee and State of New York,haveinvented new and useful Improvements in Beet-Cultivators, of which thefollowing is a specification.

This invention relates to that class 'of cultivators which consist of awheel frame to which the cultivating tools or devices are at-y tachedand which are principally employed for cultivating beets, potatoes andother small plants. j

The objects of this invention are to provide the machine with simple andconvenient devices Whereby the wheels and the cultivating tools areadjusted, whereby the tools are held in position and whereby theirmovement is controlled.

In the accompanying drawings consisting of two sheetsz-Figurelis a topplan View of my improved cultivator. Fig. 2 is a longitudinal sectionalelevation thereof, on line .fr-, Fig. '1. Fig. 3 is a sectional rearelevation of a portion of the left handshaft and connecting parts of themachine, on an enlarged-scale. Fig. 4 is a longitudinal verticalsection,on an enlarged scale, through both shafts, in line y-y, Fig. l.Fig. 5 is a sectional rear elevation of a pair of the cultivating d-isksand supporting parts. Figs. 6 and 7 are perspective views of the twoparts of the clamp inwhich the stems of the cultivating disks or toolsare adjustably secured. Fig. 8 is a longitudinal section, on an enlargedscale, through one of the clamps to which the cultivating tools areattached. Fig. 9 is a horizontal section in line -w, Fig. 8.

Like letters of reference refer to like parts in the several figures.

A represents the rear cross bar of the draft frame provided withforwardly extending thills A', a whiffletree a, and 'two rearwardlyextending bars B on which the two shafts or axles C C are supported. Thetwo axles are arranged one behind the other and each carries one of theground wheels D D the wheel D being mounted on the foremost axle O andthe wheel D on the rearmost axle C', which latter is arranged at a shortdistance behind the axle C. Each axle extends across the Serial No.401,759. (No model.)

machine nearly to the ground wheel mounted on the other axle. Both axlesrest upon each of the bars B -near the rear end thereof and e length onthe supporting bars B, whereby the distance between vthe Yground wheelscanbe increased or reduced as may be necessary to cause the wheels toproperly run between the rows of plants.

F F and E F represent two pairs of cultiyvating tools whichare-arrangedin rear of the axles and attached to the latter bylongitudinal draft bars G G', the pair of tools E-being attached to theaxle C by the bar G and the pair E to the axle O by the bar G. draftbars is attached to its axle vby a cross head H which is mounted on t-heaxleand consists of a sleeve h and vertical arms h. formed thereon.parts which are separated byan opening in which a 'collar vl is arrangedand which are connected by arched bridge pieces t" which extend oversaidcollar. The latter issecured on the axle by a set screw so that itsposition can be shifted on the axle in the longitudinal direction of thelatter, thereby shifting the position of the cross head likewise; Thecrosshead is'held against longitudinalF movement on the axle by thiscollar, but is free to turn on the axle. The front end of each` of thebars G G is bifurcated vertically and its jaws jengage with pins ortrunnions formed on the arms h of the cross head on which the bar canswing horizontally while it can'swing vertically by a turning movementof the cross head on the axle.

its upper and lower jaws lo lo carry between them'the clamp L to whichthev cultivating tools are secured. Each of these clamps con- The frontportion Z is provided with an upright sleeve m which fits with its endsbetween the jaws la k and is secured thereto by Each of these Y Thesleeve h is composed of-two The rear end of each of Y the bars G G isalso bifurcated vertically and a bolt m', which passes through thesleeve and these jaws. The rear portion Z of the clamp is provided inits front face with a semi-cylindrical upright recess fn which fits overthe rearwardly projecting semi-cylindrical portion of the sleeve m andis secured to the front portion by bolts o. The rear face of the frontportion Z and the front face of the rear por` tion Z of the clamp formthe contiguous faces of these parts and are each provided with twosemi-cylindrical vertical recesses p p which are arranged on oppositesides of the center line of the clamp and in which the vertical upperportions q of the stems Qyare clamped to which the cultivating tools areattached. These tools may consist of toothed spiders R, as representedin the upper part of Fig. l, or of disks R', as represented in the lowerpart of the same -figure. In cultivating small plants, spiders areusually employed in the earlier stages of the cultivation and disks inthe later stages. Each machineis preferably provided with a fullequipment of these different tools.

The stems Q extend from the clamp first downwardly and thenhorizontally, so as to form at their lower ends cranks or elbows whichcarry the cultivating tools on their lower horizontal portions q.preferably bent outwardly between their lower horizontal portions andtheir upper vertical portions to clear the row of plants. By turning theupright portion q of the stem in its socket in the clamp, the angle ofthe disk or spider to the line of draft can be changed and the distancebetween the two members of thesame pair can be increased orreduced. Thetools can also be reversedso as to turn their concave sides inwardly oroutwardly, as may be required. A removable sleeve q2 is 4preferablyinterposed between each disk or spider and the collar Q3 on the lowerpart of the stem, so that by changing these sleeves for longer orshorter ones, or removing them altogether,the distance between the twotools of a pair can be regulated.

S represents a cross bar which extends through openings s formed in therear portions Z of both clamps and which is secured therein by setscrews. This cross bar holds the two clamps and the two pairs ofcultivating tools at a certain distance apart and com.- pels both pairsto move horizontally together in swinging on their cross heads. Thecross bar also holdsv the two clamps parallel with the axles althoughthe draft. bars G G may stand at an angle to the line of draft and thesleeves m and bolts m of the clamps permit the clamps to pivot in thebifurcated rear ends of the draft bars as the latter swing horizontally.

T represents the handles which are secured with their lower portions tothe rear ends of the jaws lc 7a of the draft bars G G and ex- The stemsareM tend upwardly and rearwardly therefrom. The operator walks behindthe machine and controls the course of the cultivating tools by thesehandles. The tools are attached to the wheel frame by the hereindescribed devices in such manner that they can be easily ad justed tothe required work and that the operator can guide them with little eort.

I claim as my inventionl. The combination with the draft frame, of axlesupports secured to the draft frame and extending rearwardly therefrom,two axles each carrying a ground wheel and resting one behind the otherupon the rear portions of said supports, caps resting upon both axlesover each support, and bolts passing through the caps and supports andclamping the axles between them, substantially as set forth.

2. The combination with the'draft frame, the axle, the draft bar and thecultivating tool attached thereto, of a cross head composed of t-wosleeves arranged side by side on said axle and connected by a bridgepiece, a set collar arranged on the axle between the sleeves of thecross head, and supports on one of said sleeves to which the front endofhe draw bar is pivoted, substantially as set Orth.

3. The combination with the wheeled frame, of longitudinal draft barspivoted at their front to the frame by vertical pivots, tool supportsattached to the rear portions of the draft bars and provided withvertical sockets and horizontal openings, cultivator tools provided withupright stems which are secured in said vertical sockets, and a.transverse bar which is secured in the horizontal openings of both toolsupports, substantially as set forth. Y

4. The combination with the draft bar having a bifurcated rear end, of aclamp com` posed of a front and rear portion, one of said portions beingprovided with a sleeve fitted between the ends of the draft bar and witha bolt passing through said sleeve and the ends of the draft bar,substantially as set forth.

5. The combination with the draftbar having a bifurcated rear end, of aclamp composed of a front and rear portion, one cfsaid portions beingprovided with a sleeve fitted between the ends of the draft bar and witha bolt passing through said sleeve, and both parts of the clamp beingprovided in their contiguous faces, on both sides of said sleeve, withrecesses in which the tool holding stems are seated, substantially asset forth.

"Witness my hand this 1st day of August, 1891.
